After
programmed to executive memory using ICSP, it must
be verified. Verification is performed by reading out the
contents of executive memory and comparing it with
the image of the programming executive stored in the
programmer.

 2010 Microchip Technology Inc.
Step 14: Repeat Steps 8 through 13 until all 16 rows of executive memory have been programmed.
Step 1: Exit the Reset vector.
Step 2: Initialize TBLPAG and the Read Pointer (W6) for TBLRD instruction.
Step 3: Initialize the Write Pointer (W7) to point to the VISI register.
Step 4: Read and clock out the contents of the next two locations of executive memory, through the VISI register,
Step 5: Reset the device internal PC.
Step 6: Repeat Steps 4 and 5 until all 1024 instruction words of executive memory are read.

Reading the contents of executive memory can be
performed using the same technique described in
Section 3.8 “Reading Code
A procedure for reading executive memory is provided
in
is set to 80h, such that executive memory may be read.
The last eight words of executive memory should be
verified with stored values of the Diagnostic and
Calibration Words to ensure accuracy.
